To all 'whom it may concern:

Be it known that I, WM. GOODWIN, of New Haven, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Machines for Making Cement Pipe; and l do hereby declare the following to be a full, clear, and exactfdescription. of the same, when taken in connection with the accompanying drawings and letters of reference 4marked thereon, and which said drawings con-l stitute part of this specification, and represent, in-' Figure 1,a' sectional side view; Fig. 2, a plan view, and in Figs. 3 and 4 detached parts to illustrate the operation. and-construction of the working parts of my improvements.

.-My invention relates to improvements in machinery for making drainor watertpipe iii' the composition of which hydralic cement v,forms the principal ingredient, and commonly called ceinent pipe.77

Ordinarily this pipe is made by placing the stock. into'a flask and tamping it-by hand-#a laborious and tedious operation. To` overcome or to do away with this labor is the principal object of my invention, which consists inan automatic mechanism forfeed'ng and pressing the stock.

A is a flask, of any common orknown coin` struction, set upon-a base or table, B, its inten nal diameter the sameas the external diameter of the pipe-to he formed within the said flask, and resting upon the said table isa ring, a, to form one end of the pipe, and may be of any form best adapted to form a perfect joint between two sections of pipe.

G is the core, constructed in the following manner, and designed to be raised duringA the procesrsCof filling the ask: I form thecore of metal the diameter designed for the interior of the pipe. Upon the top of the core I fix ahead, D, (seeFig. 1,) so that it may be` tnrnedor re- Volve without revolving the core by passing a spindle, E, through the two, square through v the advantage of the shoes overrolis.

the head and round through the core, as indicated in the said Fig. 1 and by means of which the head may bemade to revolve, as hereinafter shown. To the said head Ifadj ustably tix one ormore shoes, F. (See Figs. l and l-enlarged in Fig. 4.) These shoes should he wide enoiigh to nearly lithe space between the core and case, as in Fig. 4., 'so that they may bear upon the whole surface of the stock. 'lf rollsl were used instead of shoes, thatpart ofthe stock next to the case could notice reached. Hence The shoes are hung tothe head D, as seen inFig.

'1, upon a pivot, c,and are adjusted bythe screws d as more or less inclination is required..

' v To thespindle E, lattach a rod or shaft, G,

in such v mannenthat the shaforovolvingwwiill "iso'cause the head ofthe core to revolve,.

and also so that it may be readily detached. The said shaft .G is supported in proper bearings H H, and made to revolve by means ot' the pulley I. As the stock is fed into thefilas-h the shoes revolving press it down and graduallyrise as the flask is filled, drawing up the Y core until the Hash is lled. Then detach the shaft from the head, remove the head, and form thenpper endiot" the pipe the reverse ot the lower end, so that the sections will t tou .getheln This may be done in any convenient manner.

To .make my machine self-feeding or to regu late the quantity of stock to each `revolution -ot' the shoes, I form a metallic ange, f, on the regulating the quantity of steeg.,A Qlilgsn,

much will pass through as can pass uudergthe, ange.. Bydepressing the shoe the depthof the stock will ne proportionately increased, or y if 'the shoe is raised the depth. wilijbele'ss.

After the pipe is finished the corev maybe drawn vout or depressed by means of a screw out upon the shaft G revolving in a hin ed nut, K. This nut, as seen in' Fig. 2, mayz e opened or closed to engage or disengagethe screw for the purpose above mentioned, or, if

' ing.

necessaryhthe saine screw mayused to raisel e the core and shoes during the ,operation of ll- Lplace several flasks, A, around a column, L, which supports a crane, M, on which are the bearings H, and through thev said column set the driving-shaft through which to carry power to the pulley I.- When one `section is com y pleted, carry the core to the next flask byswingf ing thepcraue, which supports 'the core suspended, and so on from ask to ilask as each :are finished, Vwhile other. hands remove the in ished pipe; for, instead4 of swinging the crane, thetable B may b'e set' vupon trucks' so as to turn; 'but'I prefer the swinging crane, except it be in places where'it'- is desirabledto take the finished pipe all away-at onepon't. Then thetable would be best. `I therefore'illustrate the-two combined in one machine.

rfkdo. not claim raising the core during the opera-tionof` filling the flask; but

What l do claim as of my invention, an@ desire to secure by Letters Patent, is'

. 1. The construction and arrangement of the shoe 'or shoes F with a. core' and flask, when .the said core and shoes frise as the flask becomes iilled, substantially as and for the purpose specified.
